Struct sgx_tstd::untrusted::fs::Permissions

pub struct Permissions(_);

Representation of the various permissions on a file.

This module only currently provides one bit of information, readonly, which is exposed on all currently supported platforms. Unix-specific functionality, such as mode bits, is available through the os::unix::PermissionsExt trait.

Methods

impl Permissions

pub fn readonly(&self) -> bool

Returns whether these permissions describe a readonly (unwritable) file.

pub fn set_readonly(&mut self, readonly: bool)

Modifies the readonly flag for this set of permissions. If the readonly argument is true, using the resulting Permission will update file permissions to forbid writing. Conversely, if it's false, using the resulting Permission will update file permissions to allow writing.

This operation does not modify the filesystem. To modify the filesystem use the fs::set_permissions function.

Trait Implementations

impl PermissionsExt for Permissions

fn mode(&self) -> u32

Returns the underlying raw st_mode bits that contain the standard Unix permissions for this file.

fn set_mode(&mut self, mode: u32)

Sets the underlying raw bits for this set of permissions.

fn from_mode(mode: u32) -> Permissions

Creates a new instance of Permissions from the given set of Unix permission bits.

impl Clone for Permissions

fn clone(&self) -> Permissions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for Permissions

fn eq(&self, other: &Permissions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Permissions) -> bool

This method tests for !=.

impl Eq for Permissions

impl Debug for Permissions

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
